Dynamically reprogrammable nonlinear Pancharatnam-Berry phase via ferroelectric nematic liquid crystals: a new paradigm for reconfigurable nonlinear optics

{{output}}
A dynamically programmable, nonlinear beam-shaping and steering system is demonstrated, based on photopatterned, electrically controlled, ion-doped liquid ferroelectrics. This innovative approach elevates the linear liquid-crystal Pancharatnam-Berry optics to ... ...
